George Zimmerman listens to his defense counsel Mark O'Mara, left, and Don West, center during his trial in Sanford, Fla. July 10, 2013.

The George Zimmerman case should never have been brought. Saturday night after the “not guilty” verdict was delivered, State Attorney Angela Corey justified bringing the case “to put the facts out there.” But criminal cases should never be brought simply to put the facts before the public.

No one should be charged with a crime unless prosecutors themselves really believe that the person committed a crime.

Yet, the prosecution and their own experts’ language consistently showed a lack of certainty. Prosecutors aren’t supposed to bring cases where the best they can say is that something might “possibly” have happened or that there was a “chance” that it did.

Usually defense attorneys are the ones trying to get prosecution witnesses to concede that alternative explanations might be possible. In the Zimmerman trial, even the prosecution couldn’t get definite statements out of their own witnesses.

The case was so weak that the local Sanford District Attorney refused to bring charges against Zimmerman. That is why, on the orders of the governor, an outside District Attorney, Angela Corey, had to be brought in to handle it.

Sanford Police Chief Bill Lee was fired because he also refused to charge Zimmerman with a crime.

Even the lead detective on the case, Christopher Serino, told the jury he believed Zimmerman's version of the events.

Many readers might be surprised to learn that 17-year-olds are almost 50 percent more likely to commit murders than 28-year-olds such as Zimmerman.

Other parts of the prosecution's case could only be described as an attempt to distract jurors. For example, much was made of the class Zimmerman took at Seminole State College that taught by Professor Alexis Carter.

The key was, supposedly, that Zimmerman really understood Florida’s “Stand Your Ground” law. Prosecutor Richard Mantei told the court that Zimmerman's legal studies would help jurors understand his "state of mind" and "ambitions and frustrations" before the shooting.

One could debate about whether Zimmerman remembered the part of that lecture from the class. Nevertheless, it was really completely besides the point for the same reason that the defense never referenced the law: with Zimmerman on his back and Trayvon Martin holding him down, he had no option to retreat.

None of the testimony ever explained why the “Stand Your Ground” law was even relevant to Zimmerman’s actions.

The prosecutors’ biggest problem was that they had to do more than convince jurors that their version of events was “likely,” and they never come close to doing that.

Instead, they had to show that their claims about Zimmerman were true beyond a “reasonable doubt.” To put it differently, to say something is “likely” just means that there is over a 50 percent chance it is true. To say something is beyond a reasonable doubt means that it is much closer to 100 percent.

This case should never have been brought by prosecutors, but they let politics influence their decision.
